#3481 — Can I display tics to show the value of my paramter.

I a working with set param. If f is my dummy variable, can I display tics on 
the plot at f=1, f=10 etc? Each tic should by accompanied by the values 1, 10 
etc.

Something like

  set samp 30

   x(f) = f/10 * sin(f/5)
   y(f) = f/10 * cos(f/5)

  plot  sample [f=1:30] "+" \
  using (x(f)):(y(f)):(sprintf("%.f",f)) with labels point pt 1

? The stable gp version does not (yet) have an individual increment
specifier for the sampling range. You can work around that with a
prefabricated named datablock (see "help inline data").

  set table $samp1
  set samp 50
  set xr [1:50]
  plot "+" us 1 with table
  unset table

Now you have the numbers 1 to 50 in $samp1, which you can plat like
a normal ascii file.

Thanks, this works but I want a logarithmic set of labels. I am happy like 
this:

set sample 30
set trange [1:30]
x(f) = f/10 * sin(f/5)
y(f) = f/10 * cos(f/5)
set param
set dummy f
set label "10" at x(10), y(10)
set label "20" at x(20), y(20)
# etc.
plot x(f), y(f)

Bye,

  set table $samp1
  set samp 11
  set xr [0:10]
  plot "+" us (2**$1) with table notitle
  unset table

  plot  $samp1 using (x($1)):(y($1)):(sprintf("%.f",$1)) \
		with labels point pt 1
  set samp 100
  rep "+" using (x($1)):(y($1))

That way you don't use that crummy parametric mode, and don't have
to retype all your labels for every new plot.
